Lack of sleep could fry your brain cells

A lack of sleep wouldn't only make you feel groggy but also injure your brain. A new study has revealed that 25 percent of brain cells could die after prolonged sleep loss.

"We now have evidence that sleep loss can lead to irreversible injury," a researcher said. He noted that mice were protected by a protein if they lost a little sleep but began to die when it became a habit. "This suggests to us that we are going to have to look very carefully in humans."

Researchers also mentioned that catching up on sleep over the weekends won't make much of a difference either. Further studies are required in this matter and the research may also led to medicines aimed to help people with their irregular sleep patterns.
